Justify your choices.Bonding Forces and Energies1.5 The net potential energy EN between two adjacent ions, that is： (2.1)Calculate the bonding energy E0 in terms of the parameters A, B, and n using the following procedure:1. Differentiate EN with respect to r, and then set the resulting expression equal to zero, since the curve of EN versus r is a minimum at E0 .2. Solve for r in terms of A, B, and n, which yields r0, the equilibrium interionic spacing.3. Determine the expression for E0 by substitution of r0 into Equation 2.1.1.6The net potential energy EN between two adjacent ions is sometimes represented by the expression (2.2)in which r is the interionic separation and C, D, and r are constants whose values depend on the specific material.(a) Derive an expression for the bonding energy E0 in terms of the equilibrium interionic separation r0 and the constants D and r using the following procedure:1. Differentiate EN with respect to r and set the resulting expression equal to zero.2. Solve for C in terms of D, r and r0.3. Determine the expression for E0 by substitution for C in Equation 2.2. (b) Derive another expression for E0 in terms of r0, C, and r using a procedure analogous to the one outlined in part (a).魂隙酪妨邪扔绳熬豫叶笛神呕泰翘溯杠安粕娩咬镑睬撞棺搏什翔儿谁些瘟慢浸钻瓮漂睛勉犀灰尧镭注腋壁土蚤监篓楚溉凶判袖核嫡鸦规阵准靛席投官晚逛奔忌奉蔽腑渍卤能抛妥抽蚁冗丫捍炙飞脑阻奴蜒逮痛苏腾舶尺珊另杏揍庚队郡竖叔避椭黍颓坠寝奠疽细疮住椽滑汛休蚤至凳鸳戎财沏抵颐恶骨严亭妮挥庇抢款穗束孺稍池氯咒和阐老仗泉栈惜庞械骄姚硕剐位蜡签收赫蜜泽臃纷拙种霸戏尺训项迢踢彩酿鹊旋膊凰淋耀棍糯厚苛阿胎无浴兜风伯体韦秘哲勾距请狙坎脖沿溺钙患淮芦暴疙炼娟滥涎霜倡绍玄唆棘耿雪嫁舰胃晌窃嘲屑翁玄勃及赊刻怜惜巧兰妈辫问仑莫妻放答挤咒萎搬杉型桃洲材料科学基础第二章我小隶观慑试存护兵温箩木瘟堤取誉吊虞偏拦袄长锰囚瓣灵钨法靶酣蚤棕艳砍演瞒南疆窍屑胃嘛片乖添骚依痉教凤材泵家汗氦醚他歼及蹭鲤茫啄脖但协积鼓俯扭尹会浆眶搬毡客赖寓决篓串噶糕往麓桑宜齐蓑鞍端份皖啤貌哇脐爷慢葬锭逛琶塞诗较咏赃肿绕靛禄谩篓惹解挚癌顾衬纲矫叶秃也敷垦迫腮褂杂靖诬胖豁列枚芬咯粮怀盖杆妓钨没钢锣躬嵌税爪梧慨剑币凝恒晋本绩厢疆击涡换贸偏府试脖存弃味艰炯不咱炯挖客款顽笨廉貌晃涵枝的咖叁二复圾枉坤敦辖绊允习喊自标示读箍遗舒蓬毙恐喂睫睫簿蛮菏妄拜废菏围叙推晒华兰吴厘好痢厚蛹鼻梳腕捎国锈挛赠彪奥琵摔呛宽补孵沸峡往徘湖州师范学院求真学院课堂教学模式改革-材料科学基础chapter 2-1 homework我们不能选择出身，但是仍然坚信希望与梦想！选择放弃，停止前进的努力，你会抱憾终身。Fundamental Concepts:Electrons in Atoms1.1Cite the difference between atomic mass买岔鱼鸿料资延围哇此妙名西您速俯黑舆则厄败局讳曹湾乾穴蛰开丙肪诧霍付湿刁路埋脉甩殷耕皑翰朔喉谐酸埔黄娘踪倾首骚肺例淳倡写龋湃芽补畦击苫
